Birth Control Pills: Timing and Effects on Menstrual Regulation

Oral contraceptives for menstrual regulation?

I started taking oral contraceptives to regulate my menstrual cycle.
My doctor advised me to begin taking 21 pills on the third day of my cycle each month.
However, I found online that many people stop taking the pills for seven days before starting a new pack.
I'm concerned if my doctor's method will affect the regulation of my cycle and the contraceptive effectiveness.
I began taking the pills in November, starting on the third day, and after finishing the 21 pills, my period started on the third day after stopping.
In January, after finishing the 21 pills, I experienced three days of continuous bleeding that was bright red and unlike my usual menstrual blood.
Does this affect the contraceptive effectiveness? The contraceptive I am using is Qlaira.

Understanding birth control pills, particularly their timing and effects on menstrual regulation, is crucial for anyone considering or currently using them. Birth control pills, commonly referred to as oral contraceptives, are designed to prevent pregnancy and can also help regulate menstrual cycles. The way these pills are taken can significantly influence their effectiveness and the user's menstrual health.

In your case, your doctor has advised you to start taking the pills on the third day of your menstrual cycle and to continue for 21 days. This method is indeed a common practice, as starting the pill during your period can help ensure that you are not pregnant and can also help in regulating your cycle. The typical regimen involves taking one pill daily for 21 days, followed by a 7-day break during which you will likely experience a withdrawal bleed, similar to a period.

The concern you have regarding the continuous bleeding you experienced after stopping the pills is not uncommon. Breakthrough bleeding can occur for various reasons, including hormonal fluctuations, especially when starting or stopping hormonal contraceptives. The bleeding you described as "fresh blood" rather than typical menstrual blood could be a result of your body adjusting to the hormonal changes induced by the pill. It is essential to note that this does not necessarily indicate a failure of the contraceptive method, especially if you have been taking the pills consistently as prescribed.

Regarding the effectiveness of the pill, it is crucial to take it at the same time every day to maintain consistent hormone levels in your body. If you miss a pill or take it late, this can reduce its effectiveness and increase the risk of unintended pregnancy. Since you mentioned that you are following your doctor's instructions and taking the pills as directed, you should be well-protected against pregnancy.

However, if you experience unusual bleeding or any other concerning symptoms, it is essential to consult your healthcare provider. They can assess whether the bleeding is a normal side effect of the pill or if it requires further investigation. Additionally, if you have any concerns about the specific brand of the pill you are using, such as "祈麗安" (Qilian), discussing these with your doctor can provide clarity and reassurance.

In summary, starting your birth control pills on the third day of your cycle as prescribed by your doctor is a valid approach and should not negatively impact your menstrual regulation or contraceptive effectiveness, provided you take them consistently. If you experience any unusual symptoms, such as prolonged or heavy bleeding, it is always best to seek medical advice to ensure everything is functioning as it should. Regular follow-ups with your healthcare provider can help monitor your health and adjust your contraceptive method if necessary.
